FIG. 2 is a flowchart showing a method of fraud protection 200 with a user device 100 such as a mobile device, according to some embodiments of the present disclosure. At step 210, a mobile application on the mobile device 100 may be executed or activated. In some embodiments, user device 100 may be configured to receive a user input to execute the mobile application. In some embodiments, the mobile application may be a fraud protection application or a mobile banking application, such as a Capital One® mobile application, or any type of application including a fraud protection function. For example, in some embodiments, user device 100 may be configured to activate a fraud protection function within the mobile application. In some embodiments, the mobile application may be a photo application configured to capture digital pictures or images (still or moving). In some embodiments, such as when user device 100 is a home assistant, step 210 may include activating an image capture function directly or indirectly, such as by recognizing user speech spoken into a microphone of the home assistant.

At step 220, user device 100 may capture, using the camera module 130, one or more pictures of a physical communication, such as a written communication or a printed communication (e.g., a piece of mail). In some embodiments, if the user uses a mobile banking application with a fraud protection function, the mobile application may be configured to direct the user or provide instructions to the user to take pictures of every page of a received piece of mail, including the envelope. In some embodiments, the mobile application may be configured to provide instructions to the user to take one or more pictures of a screen of a user device showing an electronic message (e.g., an email) in question. In some embodiments, if a photography application such as a native camera application of the mobile device is used, the digital pictures or images (still or moving) may be saved on the mobile device for later upload. In some embodiments, the mobile application may be configured to take a screen shot while an email in question is displayed on the mobile device 100.

In some embodiments, an image capturing device connected to a computer may be used to take one or more pictures of the mail or the email in question. For example, a camera in a laptop computer may be used. In some embodiments, a home assistant device may include a camera which may be used to take pictures of the mail or the email in question. In some embodiments, an image scanning device may be configured to capture images of physical mail. In some embodiments, an image scanning device may be associated with a mail or communication provider. For example, the image scanning device may be configured to provide the user with captured images in an electronic communication (e.g., an email) and the images may be extracted from the electronic communication.

At step 230, user device 100 may be configured to send the one or more pictures of the mail or the email to a server. In some embodiments, the mobile banking application may be configured to automatically communicate with a server and transmit the pictures of the mail and/or the email to the server. In some embodiments, the mobile banking application may be configured to first ask the user to select one or more pictures stored on the mobile device and then transmit the pictures to the server.

At step 240, user device 100 may be configured to receive a calculated confidence level of fraud from the server. In some embodiments, the confidence level of fraud may be between 0% and 100%. For example, the server may determine a confidence level of fraud of the mail to be 70%.

At step 250, user device 100 may be configured to output a notification via the user interface module 140 based on the received confidence level of fraud. In some embodiments, a message may be shown to the user on the display of the mobile device or otherwise announced or provided to the user. For example, the message may be “Alert! The mail is 80% likely to be a fraud.” The message may also be “Don't worry. The mail is not likely to be a fraud.” In some embodiments, the message may include additional details concerning the subject of the mail or the sender of the mail. In some embodiments, the message may include a link or option enabling a user to learn more information concerning the subject of the mail. For example, the message may include an indication as to whether a particular mail item has been previously received by the server etc. and any other prior results or determinations made by the server or crowdsourced from other users of the platform.

In some embodiments, even if it is determined that the received mail or email is not fraudulent, the system may provide the user with recommendations related to the claimed matter via user device 100. For example, the received mail or email may be a solicitation for an extended vehicle warranty. Based on crowdsourced inputs from other users or information obtained from an external source (e.g., the Internet), the system may send a message to user device 100 suggesting the user not to purchase the extended warranty and/or provide the user with known complaints about the warranty. In another example, if the received mail or email is a marketing mail for a refinance loan, the system may give the user a recommendation of a comparable or better product from another entity (e.g., Capital One®.)

FIG. 3 is a flowchart showing a method of fraud protection 300 with a website, according to some embodiments of the present disclosure. At step 310, a webserver may be configured to provide a website for the user to access. In some embodiments, the website may be a website of a financial institution, such as the Capital One® website. In some embodiments, the website may be configured to require the user to register and login with valid credentials, so that it may provide the user with direct services. In some embodiments, the website may be configured to not require login, so that it may act as a platform for the user to send communications and upload files.

At step 320, the website may be configured to instruct the user to upload one or more image files of a mail or an email in question. In some embodiments, a link to a fraud protection function on the website may be configured to direct the user to a file upload interface where the user may select and upload image files.

At step 330, after the webserver associated with the website calculates a confidence level of fraud based on the uploaded one or more image files, the website may be configured to display a notification to the user. For example, the notification may be “Alert! The mail is 70% likely to be a fraud.” The notification may also be “Don't worry. The mail is not likely to be a fraud.”

FIG. 4 shows different modules within a server 400, according to some embodiments of the present disclosure. In some embodiments, the server 400 may be configured to include an image receiving module 410, an image analysis module 420, a database 430, a fraud analysis module 440, and an action module 450. In some embodiments, instead of being a single server, the server 400 may include a set of servers that in tandem include one or more of the mentioned modules. In some embodiments, one or more of the mentioned modules may be implemented with a group of servers. In some embodiments, one or more of the mentioned modules may be implemented with executable instructions, or with special purpose hardware, or combinations of both. For example, the image receiving module 410, the image analysis module 420, the fraud analysis module 440 and the action module 450 may include executable computer programs based on a computer programming language, such as Python™. In another example, the image receiving module 410, the image analysis module 420, the fraud analysis module 440 and the action module 450 may be implemented with hardware circuit, such as field-programmable gate array (FPGA), or application-specific integrated circuit (ASIC). The database 430 may be implemented with commercial software such as the Oracle® database, or with open source software such as the Apache® project.

The image receiving module 410 may be configured to communicate with a mobile device and receive one or more image files from the mobile device. In some embodiments, the image receiving module 410 may be configured to accept an image file in different formats, such as JPEG, PNG, GIF, TIFF, BMP, etc. In some embodiments, the image receiving module 410 may be configured to check whether or not the received image file is corrupted. If it is determined that the file is damaged, the image receiving module 410 may be configured to notify the user and ask for a replacement image file.

The image analysis module 420 may be configured to extract text and/or one or more figures from the received image file. In some embodiments, the image analysis module 420 may be configured to use optical character recognition (OCR) techniques to extract text from the image file. In some embodiments, the image analysis module 420 may be configured to isolate one or more figures from the image file. For example, the one or more figures may include a logo, a signature, a photo, etc.

The database 430 may be configured to store pre-defined fraud-related information. In some embodiments, the database 430 may be configured to store one or more keywords or phrases and a corresponding likelihood of fraud. For example, a certain phone number may be pre-determined to be associated with a known fraud. Thus, the database 430 may be configured to store this phone number and a likelihood of fraud of 100% for this phone number. In some embodiments, a certain arrangement of distinct keywords may be related to a potential fraud. For example, groupings or combinations of keywords, or keywords of a certain frequency may be contributing factors to a calculation of a confidence level of fraud. In some embodiments, the presence of a specific keyword may trigger additional analysis. For example, a first screening may indicate the text contains a particular keyword, which may lead to a second screening using additional criterion. In some embodiments, the database 430 may be configured to store contact and identity information associated with one or more legitimate entities. For example, the database 430 may be configured to store a verified mailing address and a genuine logo of a legitimate company.

The fraud analysis module 440 may be configured to calculate a confidence level of fraud based on the extracted text and/or figures. In some embodiments, the fraud analysis module 440 may be configured to search the extracted text and compare it to one or more pre-defined keywords with high likelihood of fraud stored in the database 430. For example, the fraud analysis module 440 may be configured to determine whether any text matches a known fraudulent phone number. In some embodiments, the fraud analysis module 440 may be configured to compare one or more isolated figures from the image file to a legitimate figure stored in the database 430. For example, the fraud analysis module 440 may be configured to compare a company logo appearing in the mail to a genuine company logo stored in the database 430. In some embodiments, the fraud analysis module 440 may be configured to send a request to an external source and obtain information relevant to the extracted text and/or figures. It may then determine a validity of the extracted text and/or figures based on the obtained information. For example, a particular item of mail may inform the user of an award from a class-action lawsuit. The fraud analysis module 440 may then communicate with an external source (e.g., the Internet) to verify the information in this particular mailing and/or create one or prompts to the user to help the user determine whether the user is even part of the class. In some embodiments, the fraud analysis module 440 may be configured to check the transaction history associated with the user to determine if the user is involved in the matter claimed in the mailing or the email. For example, if it is determined that the subject of the class-action lawsuit is a particular product, the fraud analysis module 440 may determine if the user has ever purchased the product based on the transaction history.

In some embodiments, the fraud analysis module 440 may be trained with a machine learning algorithm. For example, the fraud analysis module 440 may first receive human inputs on the presence of fraud schemes for a large number of mails and/or emails. Then the fraud analysis module 440 may create an algorithm with machine learning techniques as it learns from the human inputs. Once the algorithm is implemented, the fraud analysis module 440 may determine one or more fraud vectors from the extracted text and/or figures to be checked and return a calculated confidence level.

The action module 450 may be configured to perform a pre-defined action in response to the determined confidence level of fraud. In some embodiments, the action module 450 may be configured to send a message containing the determined confidence level of fraud to a mobile device used by the user, or display a notification on a website used by the user. For example, the user may receive a message such as “There is a 80% chance of this mail being a fraud.” In some embodiments, if it is determined that the user has initiated a high risk transaction based on the information provided in the mail or the email in question, the action module 450 may be configured to perform a more proactive action, such as placing a flag on an account of the user, or even freezing an account of the user. For example, if the confidence level of fraud exceeds a threshold value, there may be a prompt where the user is asked if he or she has initiated or performed any transaction related to the mail or the email in question which may jeopardize his or her account. If yes, the action module 450 may be configured to place a flag on the account or even freeze the account.

FIG. 5 is a flowchart showing a method of fraud protection 500 with a server, according to some embodiments of the present disclosure. At step 510, one or more pre-defined keywords and a corresponding confidence level of fraud may be stored in the database 430. For example, a certain phone number may be pre-determined to be associated with a known fraud. Thus, the database 430 may be configured to store this phone number and a confidence level of fraud of 100% for this phone number. In some embodiments, the database 430 may be configured to store information associated with one or more legitimate entities. For example, the database 430 may be configured to store the mailing address and genuine logo of a legitimate company. In some embodiments, an administrator of the system may enter the keywords and store them in the database 430. For example, a fraud protection unit at a financial institution may compile a list of known or suspected frauds and relevant keywords and the administrator of the system may enter them into the database 430. In some embodiments, the system may obtain information from an external source (e.g., the Internet) and perform machine learning to determine one or more fraud-related keywords and store them in the database 430. In some embodiments, a fraud analysis model may be stored in the database 430. The fraud analysis model may be developed with machine learning techniques based on a large number of mails or emails, each of which may be identified as either fraudulent or legitimate by human instructions.

In some embodiments, crowdsourcing may be used to collect keywords associated with fraud. For example, the system may be configured to collect fraud information from multiple sources. In some embodiments, one or more users may report a suspected or known fraud to the system. The system may store relevant keywords from the user reported fraud in the database 430 and assign a likelihood of fraud. If it is a known scam, the likelihood of fraud may be 100%. If it has not been verified, the likelihood of fraud may be determined based on the number of users reporting. In some embodiment, the system may be configured to receive fraud information from another financial institution, a government regulatory agency, or a law enforcement agency. In some embodiments, the system may be configured to continuously update the fraud information stored in the database 430 based on received information from users. In some embodiments, the fraud analysis model stored in the database 430 may be updated with the received crowdsourced information. For example, the crowdsourced user inputs may act as additional human teachings to the system for it to further adjust the fraud analysis model.

At step 520, the image receiving module 410 may be configured to receive one or more image files from a user. In some embodiments, the image receiving module 410 may be configured to accept an image file in different formats, such as JPEG, PNG, GIF, TIFF, BMP, etc. In some embodiments, the image receiving module 410 may be configured to check whether or not the received image file is corrupted. If it is determined that the file is damaged, the image receiving module 410 may be configured to notify the user and ask for a replacement image file. In some embodiments, the image file may be uploaded by the user with a mobile device. In some embodiments, the image file may be uploaded by the user through a website. In some embodiments, the image file may be scraped from a user's electronic messaging account. For example, in some embodiments, a user may receive electronic communications including images of physical mail pieces prior to or in association with actual mail delivery. In some embodiments, access may be granted to the user's messaging account, from which image receiving module 410 may be configured to obtain the images. In some embodiments, image receiving module 410 may receive one or more image files from a third party service (e.g. a distribution service) prior to a mail piece being delivered or based on the mail piece being processed in a distribution channel.

At step 530, the image analysis module 420 may be configured to extract text and/or one or more figures from the received image file. For example, the image analysis module 420 may be configured to use optical character recognition (OCR) techniques to extract text from the image file. In some embodiments, the image analysis module 420 may be configured to isolate one or more figures from the image file. For example, the one or more figures may include a logo, a signature, a photo, etc. In some embodiments, the image analysis module 420 may be configured to parse the extract text and store different parts in different categories. For example, the name and address of the sender of the mail may be labeled as “sender entity.”

At step 540, the fraud analysis module 440 may be configured to calculate a confidence level of fraud based on the extracted text and/or figures. In some embodiments, the fraud analysis module 440 may identify the most relevant aspect of the mail or email for determining fraud. For example, the validity of the sender information on the envelope of the mail or the header information of the email may be verified first. For example, the fraud analysis module 440 may check if the sender's name, physical address, or email address are legitimate. In some embodiments, the fraud analysis module 440 may be configured to compare one or more isolated figures from the image file to one or more legitimate figures stored in the database 430. For example, the fraud analysis module may be configured to compare a company logo appearing in the mail to a genuine company logo stored in the database 430.

In some embodiments, the fraud analysis module 440 may be configured to search the extracted text and compare it to one or more pre-defined keywords stored in the database 430, whereas the one or more pre-defined keywords correspond to high confidence level of fraud. For example, the fraud analysis module 440 may be configured to determine whether any text matches a known fraudulent phone number. In some embodiments, the fraud analysis module 440 may be configured to send a request to an external source and obtain information relevant to the extracted text and/or figures. Then fraud analysis module 440 may be configured to determine a validity of the extracted text and/or figures based on the obtained information. For example, the mail may inform the user of an award from a class-action lawsuit. The fraud analysis module 440 may then communicate with an external source (e.g., the Internet) to verify the information in the mail. In some embodiments, the fraud analysis module 440 may be configured to calculate a confidence level of fraud using a fraud analysis model developed based on machine learning techniques applied to a captured image or subsets of the image.

In some embodiments, the fraud analysis module 440 may be configured to evaluate the characteristic of a potential fraud. For example, an exaggerated warning, or a call to action to do something risky (e.g., investment) may be characteristics of a potential fraud. In some embodiments, the fraud analysis model may include the characteristics of a potential fraud, and may be updated with machine learning techniques.

At step 550, the action module 450 may be configured to send an indication of the determined confidence level of fraud to a user device. In some embodiments, the action module 450 may be configured to display a notification on a website used by user. For example, the user may receive a message such as “There is a 80% chance of this mail being a fraud.”

In other embodiments, the computer 700 corresponds to a physical computer.

Referring again to FIG. 7, processing may be implemented in hardware, software, or a combination of the two. In various embodiments, processing is provided by computer programs executing on programmable computers/machines that each includes a processor, a storage medium or other article of manufacture that is readable by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and one or more output devices. Program code may be applied to data entered using an input device to perform processing and to generate output information.

The system may perform processing, at least in part, via a computer program product, (e.g., in a machine-readable storage device), for execution by, or to control the operation of, data processing apparatus (e.g., a programmable processor, a computer, or multiple computers). Each such program may be implemented in a high level procedural or object-oriented programming language to communicate with a computer system. However, the programs may be implemented in assembly or machine language. The language may be a compiled or an interpreted language and it may be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program may be deployed to be executed on one computer or on multiple computers at one site or distributed across multiple sites and interconnected by a communication network. A computer program may be stored on a storage medium or device (e.g., CD-ROM, hard disk, or magnetic diskette) that is readable by a general or special purpose programmable computer for configuring and operating the computer when the storage medium or device is read by the computer. Processing may also be implemented as a machine-readable storage medium, configured with a computer program, where upon execution, instructions in the computer program cause the computer to operate. The program logic may be run on a physical or virtual processor. The program logic may be run across one or more physical or virtual processors.

Processing may be performed by one or more programmable processors executing one or more computer programs to perform the functions of the system. All or part of the system may be implemented as special purpose logic circuitry (e.g., an FPGA (field programmable gate array) and/or an ASIC (application-specific integrated circuit)).

Additionally, the software included as part of the concepts, structures, and techniques sought to be protected herein may be embodied in a computer program product that includes a computer-readable storage medium. For example, such a computer-readable storage medium may include a computer-readable memory device, such as a hard drive device, a CD-ROM, a DVD-ROM, or a computer diskette, having computer-readable program code segments stored thereon. In contrast, a computer-readable transmission medium may include a communications link, either optical, wired, or wireless, having program code segments carried thereon as digital or analog signals. A non-transitory machine-readable medium may include but is not limited to a hard drive, compact disc, flash memory, non-volatile memory, volatile memory, magnetic diskette and so forth but does not include a transitory signal per se.

In describing exemplary embodiments, specific terminology is used for the sake of clarity. For purposes of description, each specific term is intended to at least include all technical and functional equivalents that operate in a similar manner to accomplish a similar purpose. Additionally, in some instances where a particular exemplary embodiment includes a plurality of system elements, device components or method steps, those elements, components or steps may be replaced with a single element, component or step. Likewise, a single element, component or step may be replaced with a plurality of elements, components or steps that serve the same purpose. Moreover, while exemplary embodiments have been shown and described with references to particular embodiments thereof, those of ordinary skill in the art will understand that various substitutions and alterations in form and detail may be made therein without departing from the scope of the invention. Further still, other embodiments, functions and advantages are also within the scope of the invention.
